MST450D-0012-FT-N0SN-NNNN

The Bosch Rexroth Indramat MST450D-0012-FT-N0SN-NNNN from the MST Synchronous Torque Motors series is a precision-engineered Synchronous Torque Motor designed for high-torque rotary applications. This part_number delivers a Torque Range of 810 Nm - 1800 Nm at a Maximum Speed of 250 rpm, making it ideally suited for CNC machining centers, lathes, and milling equipment. Built to integrate seamlessly into demanding industrial workflows, the motor’s robust construction supports continuous operation under heavy mechanical loads. Its compact frame length D configuration optimizes torque density while maintaining precise speed regulation for metal-cutting and drilling tasks.

The motor uses advanced Liquid Cooling to maintain thermal stability during peak performance cycles. A dedicated stator cooling jacket circulates coolant at a controlled Coolant Temperature of 10 - 40°C and a regulated Coolant Pressure of ≤ 3 bars to dissipate heat effectively. Designed for maintenance efficiency, the motor features a Shaft Protection seal ring that prevents ingress of contaminants and retains lubrication oil at the shaft end. Preventive upkeep is simplified by a recommended Lubrication Interval of every 28,000 cycles, ensuring long-term reliability and minimal downtime. Its open-frame design meets Protection Rating IP00 criteria, so it is best installed in clean, indoor environments or ventilated enclosures.

Engineers will appreciate the motor’s compatibility with standard CNC control interfaces and its low mechanical backlash under variable loads. By operating within an ambient temperature range of 0 to 45°C, the MST450D-0012-FT-N0SN-NNNN maintains optimal performance without excessive reliance on auxiliary cooling. Overall, this motor delivers high torque, precise speed control, and reliable operation for heavy-duty metal-cutting and positioning applications.
